Montreal ACC question
« on: April 24, 2007, 10:31:55 PM »
Good evening...
Anyone here work at Montreal Centre? I have a question regarding Ottawa TCU. I visited Montrea ACC a couple of years ago and I remember the shift manager pointing out that Ottawa was part of a specialty known as Captials and the controllers there controlled both Ottawa and Quebec City's Terminal areas... Although this seemed odd at the time, I accepted it that within the same specialty you learned both and sat in one position or another... However, listening to the CYOW feed tonight, I KNOW I heard the same voice of the same controller talking to both aircraft in Ottawa and clearing an aircraft for a visual approach to Quebec City once the airport was in sight... How can this be? Is the same controller looking at two different displays? Please explain, I'm extremely interested... (if anyone wants to go into the archives, it would've happened sometime between 0200 and 0230Z...

Speaking of the CYOW feed, why does the archives section not have access to this feed? I went to check the transmissions I was just talking about earlier, and noticed that this feed is not listed in the pull-down menu in the archives section... any liveatc maintainers have an answer to this one?

Does anyone know why the YUL feed is down and when it will be back? Its' been down for the better part of a week and I really miss it. I'd really like to hear more about this.

No, the controller wouldn't be looking at two different displays.  The Canadian radar display systems have the ability to use inset windows, which allow us to look at different areas, or close ups of problems areas, on the same screen as the rest of our airspace.

For the terminals, they would have one terminal area on the display (typically the busier one at the time), and the other in a smaller window in one of the corners of the display.

Regina and Saskatoon used to do this all the time on weekends, before the Regina terminal was given over to the en-route controllers.

Having worked there myself a while ago, that scenario would be during a midnight shift only.

Ok, ny next question then is this... why can we hear both the controller AND the pilot then for Quebec Terminal when listening to the CYOW feed? (hearing the controller makes sense, he's probably just simulcasting on both the Ottawa Terminal and Quebec Terminal freqs, but how is it then that we can har the pilots in the Quebec Terminal Zone?)

Also, still no response to my question to the site people... why no archives for CYOW?

The new communications equipment that the ACCs and major towers have allows frequency coupling, allowing us to join up frequencies so that when an aircraft transmits on one frequency his transmission is simultaneously re-broadcast on all the other frequencies.  Works great to prevent aircraft on different frequencies from stepping all over one another, especially when you can have 8-9 frequencies at a time in some specialties.

It's all making sense now... although I assume that you can only couple up freqs when traffic is really light... otherwise, you would just have too many people waiting to talk or respond to someone wouldn't you? so I guess what this does is when you join up two sectors, you're also joing up their frequencies, but you're letting people stay on their usual freqs instead of putting them all on one freq? makes sense to me...

Actually, when it's busy is when it does the most good.  You will only have one radar controller at each sector, and he can only be talking to, or listening to, one aircraft at a time.  The system just makes sure that 3 different aircraft aren't all broadcasting at the same time on three different frequencies.

Keeping aircraft on the freqs. that they are supposed to be on, ensures that when you split off a sector, everyone is on the proper frequency.

 :roll:
IMAGINE an acc controller operating 9 Frequencies   providing airtraffic services to five Advisory airports at a time and three freqs must be free of coupling to avoid distortion and you will face three aircrafs transmiting at the same time so you must ask all flight to standby and pick one have the massage go to the other never use the phrase ( flight calling say again)
 Collect   the flight progress strips from the priting dvice and post them on flight progress board deliver  flight estimats to Adjacent FIRs  & units , response to hotlines gives Revision to Concerned personals .gives traffic infomation to ARR & DEP flight at those airport where no aproachs control established issue atc clearances to all flight at those airports listen to the read backs while the other flight on the free of coupling  Frequencies  are overriding while listening to the reading back of pilot
no Assistant  JUST IMAGINE  is that easy to be handled
 pilot :venus control  pia7525 do you read
controller: pia 7527 venus control loud and clear go ahead
pilot :pia 7525 Request  to track direct jfd point
cont : pia 7525 negative maintain the airway
pilot : venus control Confirm  negative
cont : Affirmative  negative
